It should be noted that, the corner of the fixed adsorption structure 20 is also arc-shaped, so as to avoid the problem of sharp corners, and facilitate the matching between the adjustable adsorption structure 30 and the fixed adsorption structure 20.

As shown in fig. 3, fig. 5, fig. 12 and fig. 13, in the technical solution of the present embodiment, the base plate 10 is provided with a plurality of sliding grooves 11 penetrating along a thickness direction of the base plate 10, the adjustable suction structure 30 further includes a sliding fixture block 33, the sliding fixture block 33 is disposed on a side of the base plate 10 away from the adjustable suction structure 30, and the sliding fixture block 33 passes through the sliding grooves 11 and is detachably connected to the adjustable suction structure 30. The sliding fixture block 33 is a T-shaped block, the larger end of which is disposed on the surface of the substrate 10 away from the adsorption groove, and the smaller end of which can extend into the sliding groove 11 and contact with the wall of the sliding groove 11 to form a limit in the direction of the wall of the sliding groove. The sliding fixture block 33 is detachably connected with the adjustable adsorption structure 30, so that adjustment can be performed to a certain degree, interchangeability of the sliding fixture block 33 and the adjustable adsorption structure 30 is increased, locking between the sliding fixture block 33 and the adjustable adsorption structure 30 as well as between the sliding fixture block 33 and the substrate 10 can be realized, and the adjustable adsorption structure 30 is ensured not to have play in the process of processing, so that processing problems are avoided.
